ALBANY — Weezer lead singer Rivers Cuomo suffered a partially collapsed lung, three cracked ribs and a lacerated spleen after his tour bus plunged off a wet I-90 Sunday morning.

On Tuesday, Cuomo was still recuperating at Albany Medical Center Hospital, according to the band's Web site. He had improved significantly since the day of his accident, when he could barely talk, open his eyes or move his leg.

On Monday, the singer of "Beverly Hills" and "Undone" was able to partially sit up in his hospital bed, read books and check the Internet. Cuomo is being monitored to ensure that fluid doesn't build up in his lung. Doctors determined that his blood pressure had stabilized, which indicates that his spleen is no longer bleeding. The injuries to his lung will likely not need surgery.

Cuomo was not able to move his right leg after the accident, though he did not break any bones. Koch said Cuomo jumped off a railing while playing at a gig in Toronto the night before the accident and that he didn't realize the drop was 6 feet, so that could account for the pain in his leg. He was able to wiggle some toes Monday after icing and decompression.

Doctors expected Tuesday to allow Cuomo to stand for the first time since his accident.
